Ruffalo signed for six Marvel films

Mark Ruffalo has hinted there could be more from his Incredible Hulk alter-ego after revealing he has signed a six-film deal with Marvel.

The 44-year-old takes on the role of the mean, green smashing machine in Avengers Assemble, following Eric Bana and Edward Norton's portrayals of the character.

"[I've signed on for] six, yes," he told Collider.com, adding that he would relish the opportunity to make more films with the Hulk.

"The experience too was great. I really had a good time and it was fun. I loved that group of people."

Mark previously teased that he would love to make a guest appearance in Thor 2.

"That would be cool. Thor could show me a good time in Asgard!" he joked.

Marvel Studios chief Kevin Feige previously revealed that there are no further plans for another Hulk screen outing.

"Well, no. I mean, this was the third appearance of Hulk and everything that we had and were going for, we put into Hulk's appearance in Avengers. So, I love that people are saying that and are feeling that way about Hulk, but mission accomplished at this point," he told The Huffington Post.

However, Paul Gitter from Marvel Entertainment said otherwise, due to the "phenomenal response" to the Hulk.

"If the Hulk's successful turnaround continues, Marvel will spin him off to a stand-alone [TV] programme next year, supported by a big budget franchise movie in 2015," he told Forbes.com.
